SELF-MEASURING moom-msrn'nsmo Arrm'rt'rs.

To all whom it may concern.

Be it known that I, LINNAEUB E. Bamgm,

a citizen of the United States, residing at' uid-Dispensing A paratus, of which the f lowing IS a speci cation.

My improvement relates to self-measuring liquid dispensing apparatus of the type having an elevated container from w nch the liquid dispensed flows b gravity. Such apparatus is most common y set up on the sidewalk or along a driveway for dispensing gasolene direct to the tanks of automobil es.

The ob'ect of my invention is to provide a vertica ly adjustable dischar e pipe terminating at the bottom in a disc arge nozzle or hose; said discharge pipe extending from below up into said container through a stuffing box. The apparatus .is so constructed as to insure accurate measurement under all conditions, and there are gages to determine the quantity of liquid delivered and to be delivered.

Additional advantages of my invention are a simple and easily operated apparatus adapted to rapidly deliver the quantity of liquid desired direct to an auto tank or other a vessel. 1

The apparatus also permits starting to deliver liquid on an order with enough liquid in the container to meet the maximum demand for that sale and the operator may begin delivery by lowering the discharge pipe gradually, or from time to time and so continue until the purchaser is satisfied. The quantity of liquid delivered may be accurately learned from the container gage,

whether the setting latch finally rests in a notch of the lower gage or not.

The articular embodiment of my invention se ectcd for illustration is a so-called visible liquid measuring and dispensing apparatus, (with sourceof supply and means for raising liquid from said source to the container not shown) in which Figure 1-, is an elevation of the apparatus from such a position as to show both one of the scales indicating quantity of liquid the apparatus is set to discharge and one of the scales indicating the quantity of liquid actually discharged from the container.

Fig. 2, is an ele ation of the ap aratus taken at 90 to Fig. 1 with the discharge Specification of Letters Patent.

Referring now to the drawings, E is a pedestal of such height as to' raise the container cylinder F, and other parts the desired distance: The bottom e, of the pedes- -for the tie rods e", which securel hold together the several parts of the pe estal, and also hold the pedestal itself to the bottom head f, of the liquid container cylinder F. The pedestal may be provided with one or more doors e", to afford convenient access to the interior. A scale e, shown graduated to Fig. 10, a detail, is an enlarged vertical' gallons and half gallons, is fixed to or made a partof the flange 6, or) either side of the slotted plate e Notches e, graduated to allons are provided in the edges of the ange e".'

The bottom head f, of the container is a round plate with a peripheral flange which has a groove below to receive the shell e, of the pedestal and a groove the container cylinder F. This bottom head f, has a stuffing box f, with a suitable pack-. ing f, and gland f, through which passes the dischar e pipe A, hereinafter to be described. T e bottom head f, also has an opening f,threaded to receive the upper and lower parts of the fill pipe be described and an opening f, receive the upper and lower parts of the overflow pi'pe C, hereinafter to be described. On the under side of the bottom head I, are cast two projecting lugs f, adapted to sustain the counter weight pulley a, hereinafter to be described.

The container cylinder F, as shown in the drawings is made of sheet metal with a suitable number of windows f, of transparent material so placed that the custolner can see the height of liquid in the container from his automobile next the curb from either side and from other points as desired. These windows are clamped in position by removable oblong ring plates f screws and frames f", with gaskets f f, to form a leak-tight joint. To each oblong ring plate f, is attached a scale for the liquid container. This scale, here shown graduated to gallons and half gallons, is provided with a slot f, at each end, through which the screws pass that secure the scale to the ring plate and the slots are provided to permit exact adjustment of each scale to the container cylinder;

The top head f, has a groove in the under side of its peripheral flange to receive the.

container cylinder F. Hand hole plates f, 7, are provided on the head f", to make the interior accessible for cleaning, adjustment and repairs. A vent valve H, ofany usual construction is placed on top of the top head f", at any convenient place and as shown in the drawings is on the hand hole plate f.

The top head f", is surmounted by a lamp support G. adapted .to have the usiial top globe g, and with brackets g, to support side lamps to illuminate the scales.

Tie rods f connect the top head f", and the bottom head f, and hold the container cylinder F, securely in place. It will be understood that joints are made leak tight with litharge or any other suitable way.

The fill pipe B, passing through the hole A, of the plate 6. and being connected below to the source of liquid supply (not shown) cm'ivcys the liquid through the bottom head T, he container and terminates inside near the top of the container. This upper above to receive B,hereinafter to f threaded to end is provided with a deflector b, consisting of an inverted cup or thimble firmly held in position free from contact with the pipe 13, by fpins b. This deflector causes the liquid to ow down the outside of the fill pipe B. causing the least possible agitation of the body ofthe liquid in the container cylinder The bottom edge of the deflector I; must be above the desired zero level of the liquid in the container cylinder F, so that it cannot siphon the liquid belowsaid level back to the source of liquid supply- The overflow pipe extends from the inside upper portlon of the liquid container cylinder F, down through the bottom head of the container and the hole e, of the plate e, to the source of liquid sup )ly (not shown.) At its upper end this pipe I, terminates with asleeve 6, adjustable vertically so that the upper edge of said sleeve may be permanently set at the desired zero level of the liquid-container cylinder F.

The discharge pipe A, is vertically movable in the liquid container through the stuffing box f, packing f and gland f", and is keptin exact alinemcnt by the guiding extension a, passing through the opening e, of the plate e. The guiding extension a, is integral with and extends downwardly from the bottom of an L (1.. into which L fits the lower end of the discharge pipe A. The horizontal portion of the L a. extends outwardly through the slot and between the flanges e, of the plate (2, and the hose I, is attached thereto.

To any convenient part of the discharge pipe A. or its attendant parts, is secured one end of a cable or chain a", which passes over a pulley a, whose bracket a, is secured to the rojecting lugs f, on the bottom head f. o the container. The other end of this chain a", is attached to a counter weight a of suitable weight 'to counterbalance the weight of the discharge'pipe A, L a, and guiding extensio'n a, so as to insure easy movement up and down of the discharge A setting latch D, is secured to the under side of the L a, by a ivot d, in such a man,

. nor as to oscillate at right a les to the plane passing through the aices 0 both branches of the L a. A latch bar d, is fixed by the pin d, or in any other suitable manner to the latch block d, in such'a position that the latch bar will enter any of the notches e".

when the latch D, is in engaging position.

Pointers d1, fixed to the latch bar it, near the ends thereof indicate on the scales e, the

quantity of liquid required to be dispensed by the apparatus when the latch has been setin accordance with the order. A handle. 11". is secured to the latch block a. for 0011 venience in manipulating the setting latch. The handle If. is drilled at d, to rmit the shank of the plunger d, to through its upper side; and the latch block d, is drilled 'to form a receptacle for the head of this plunger, and also to receivea spring 11". This spring tends to keep the lunger in extreme protruded position and w en the hose I, is in position for use its coupling keeps the lunger sufficiently de ressed to cause it to iiold thsetting latch against the notched scale whether in position for the latch bar d, t0 enter one of the.

notches e, or not. 1

Final adjustments for and operation of my up aratus is as follows lpon assembling the device'and-hefore it is ready for accurate measurement of liquid to be dispensed therefrom, it-is necessary to vertically adjust-the discharge scalef, of the container cylinder F, so that its zero indicationwill be levellwith the upper end of the discharge pipe when the setting latch D; is in the (zero notch of the discharge scale e Tliisadj is'tment' is made by loosening the screws which hold said scale f to the ring plate ff and with the liquid filled to the level ot-th'e top edge of the discharge pipe A. Accessfltolthe interior parts of the container cylinder F, is by means of hand hole plates f, and f. The

terminal sleeve 0, at the upper end of the position (see Fig. 1) as indicated on the I scale c". in which position-the top end of thedischarge pipe A is above the surface of vthe liquid 'wliile filling. The liquid to be I dispensed is then caused by suitable means (not shown) to How from the source of liquid supply (not shown) through the fill pi e B. into the container cylinder I. until tielcvcl ot' the liquid is raised to a level above that of the top of the overflow pipe Through the overflow pipe C. the excess liquid gravitatcs to the sourcc'of supply.

quickly and accurately bringing the level of the liquid in the container cylinder l. to 7.011) on the scale f". The setting latch D, is then lowcrcd to the amount called for as obscrvcd on the scale 'c'". the upper end of -tlic discharge pipe A. being lowered a corresponding amount bv tlie sliding of said pipc through the. stuiiing box, f, f'r'gf. in

' the bottom head f. of the container. The

, securely liquid will then how by gravity through the discharge pipe A, and the hose I, to the auto tank or other. vessel until the upper end of said pipe establishes thefina'l liquid level and indicates on the scale f", in the container, the exact amount discharged.

. In case the customer cannot make uphis mind in advance how much liquid is necessary, the .operator,may immediately begin del very by either gradually or periodically; lowering-. the setting latch and .discharge pipe ai id continue so to do until decision is finallymade'or until the auto tank or vessel is filled.

- Repeated raising of the latch-D 'slidable discharge pipe A, and attendant parts for refilling the container cylinder F,'and par tial or complete lowering of the same to draw liquid is all that is necessary to operute my invention. The counterweight makes such operation easy. In ordinary .prfictice as soon as the required quantit has "been drawn the operator will raise t e latch to B5 fill position so as to make ready for the next sale and such raising facilities com- "plete draining of the hose. Having thus described my invention what I claim as new and desire to secure by Letgo 'teis Patent is:

- 1. ,A liquid dispensing apparatus adapted to dispense liquid by gravity. having-in com bination an elevated liqu d container, an

overflow pipe terminating at its upperend 915 within said container at a predetermined level and at its lower end in a source of liquid supply. a fill pipe terminating at its upper cud within said container at a level above that of the overflow pipe and at its lower end in the source of liquid supply, a-discharge pipe terminating at its upper end within the container and at is lower end in an cxt/eriorly discharging outlet fixed to and movable with said discharge pipe. said dis- 10 5 charge pipe being manually adjustable as to height.

2. In combination with a liquid dispensing apparatus having an elevated liquid container whence the liquid may be discharged bygravity. a discliai e pipe slidableup and down through a sin mg box in the bottom head of said container. an outlet fixed to the bottom cud of said discharge pi e for delivcrilig the liquid exteriorly of tie apparall5 tus. and an cxtcnsion fixed to said discharge pipc to guide the same.

In testimony whereof I have hereunto-set in. hand in presence of two subscribing witllQHHtS. l
